The highest stature to which the Chimpanzee can attain is about four and a half feet; but as he never stands absolutely erect, he appears much shorter. His small eyes, deep sunken in their orbits, are of a dark hazel colour. The cranium, even in young specimens, is depressed, and presents, in advance of a low receding forehead, a projecting superciliary ridge. As the animal advances in years, his muzzle lengthens, his jaws develop, his skull grows more depressed; at the same time his intelligence gradually disappears, his manners become fiercer, and his disposition less tractable; in a word, the instincts of the brute regain their supremacy. Such, at least, is the statement of the best accredited authorities; as for the individuals imported into Europe, they invariably die at too early an age for any one to study their habits and character in maturity. The Chimpanzees live, it is said, in troops in the forests, or at least they congregate for the purpose of repelling the attacks made upon them by the carnaria, and to drive from their domains such other animals as may attempt to install themselves therein to their disadvantage. Their weapons are ready to their hand--stones and the branches of trees. Their diet is essentially a frugivorous one; yet they will occasionally indulge in a lizard or two, or any other reptile. Like the orangs, they construct rude beds or couches, of interwoven boughs stripped of their greenery. The negroes of Guinea, scarcely much higher in the scale of intelligence than themselves, look upon them as a _nation_, and believe that if these Men of the Woods do not speak, it is because they fear to be condemned to work or carried off into slavery, and not from incapacity. A recent traveller, whose adventures have been the subject of much discussion, and who for a considerable period enjoyed the reputation of a Mendez Pinto or a Munchausen, asserts that he discovered at the Gaboon two new species of Chimpanzees. One, called by the natives _Nshiégo-Mbouvé_, and to which he gave the scientific name of _Troglodytes calvus_, builds for himself some leafy screens of quite artistic construction upon isolated trees. He is smaller than the ordinary Chimpanzee, and _bald_.
